Secrets

 * 1) In the courtyard to the west of one of the blue keycard destination points, go towards the cliffs at the south side. You can climb these cliffs using the small section of cliffs on its west side. At the top, you can find a plasma gun. (sector 5282)
 * 2) In the room with the arachnotron on the central pillar (Secret #3), you can find a super shotgun to the northeast. In order to get it, from the high platform to the south of it, gently drop down nearby so you are on a thin edge, then hug the east wall as you head up to the super shotgun. You can also get this secret by dropping down from the northern ledge above (in the southwest part of the room with the hexagon platforms). (sector 5780)
 * 3) In the room with the arachnotron on the central pillar, get to the area to the south of that pillar and climb the steps on the west side to a red pad. From this pad, go west into the pentagram wall and you will teleport to the center of the pillar, where you can get a soul sphere. (sector 5848)
 * 4) In the room with the arachnotron on the central pillar (Secret #3), drop down into the lava to the west of the pillar. To the southwest, you can pick up a megaarmor. (sector 6234)
 * 5) At the southeast end of the main map, go on a floating platform and ride it up. Get off on the higher ground, and head northwest to the pink pad. From here, you can drop to the east to pick up two boxes of rockets. (sector 6942)
 * 6) At the southeast end of the main map, go on a floating platform and ride it up. Get off on the higher ground, get to the southeast end, and go to the tree. You can go behind the wall and head north, then press on the black wall in the back. This will lead to a minigun, ammo clips, and a box of ammo. (sector 12059)
 * 7) In the cave system near the north end of the map, make your way to the west side of the section with a lava chasm, then hop two blocks to the east. There will be a skull switch here. This will teleport you to the eastern lavafall where you can find a soul sphere. (sector 12641)
 * 8) When you get to the pink skull key, head northwest of it, staying on the cliffside, to find a heavy weapon slug and boxes of rockets. (sector 14148)
 * 9) After finishing the circular arena at the northern part of the map, exit to the north towards a teleporter. Instead of taking it, go to the tree to the left and get around it, hugging the cliffside until you find a heavy weapon slug in an alcove. (sector 14375)
 * 10) In the outside area southeast of the circular arena at the north end of the map, shoot the green switches to make blue platforms appear, then traverse the blue platforms to the other side. When you get there, turn around and climb the ledges going south, then drop down to pick up a soul sphere. (sector 14881)
 * 11) At the northwest outside area of the map, head to the northeast and go through the underpass to the area beyond with a switch. Go to the southwest part of this area and look towards the inner wall to find a button. Shoot it, which will raise a bridge where the underpass was. Head to the area to the south, then use the north lift and take it up, then through the previously blocked-off area to the north where you can get across the bridge to a quad damage powerup. (sector 15034)
 * 12) In the southeast part of the map (blue skull key area), get to the northern section with the red switch. In this area there are three square terminal columns. Go to the leftmost one and to its northwest side. There is a small yellow button on this side. Shoot it, then quickly run all the way east, then in this vent, head south. Keep heading south, staying on the high ground and climbing up to a teleporter. Take it, then head west to two health bonuses, then south and up the cliffs to a grassy section. Follow the trail of health bonuses and you will eventually reach a minigun and a tiny cacodemon, part of the set in this map. (sector 15057)
 * 13) At the northwest outside area of the map, climb the ledges at the north end, cross over a crate, and move northeast, sticking to the cliffside as until you get to an area with two boxes of rockets and a box of ammo. (sector 17310)
 * 14) In the large area following the yellow skull gate, go through the caves to the north, then climb up and head south and east to the area with pink-lighted columns. Head all the way to the east, past the next entrance, then north to get a green armor and medikits. (sector 17749)
 * 15) At the southern end of the map with the arachnotron conveyors, get onto the one at the east side, then gently drop down to the west so that you are on the bricks just below the conveyor. Then go under the conveyor and head north into the dark passage. Use the yellow skull switch to open a barrier, then enter the room with the rotating cyberdemon. Press all the switches in the area to shrink the cyberdemon, which is a collectible and part of the set. (sector 22747)
 * 16) At the southwest end of the main map, get to the grassy areas far to the west and head south as much as you can. Behind the tree, you can climb up some cliffs, and you will find a cave doing so. Enter the cave, and you will have to run to the switch in the nukage as well as the island in the middle to get one of the tiny monster collectibles in the map, which is a tiny baron of Hell. (sector 24432)
 * 17) At the teleporter leading to the final arena at the west end of the map, you may notice a computer area map and a railgun on a high cliff.

 * 20) At the southwest end of the main map is a large crater with an arena below. One of the high rocks at the west end of the arena has a backpack, which can be reached from the left side where the grassy area is, though you have to be nearly precise when dropping down. (thing 2959)
